Résumé
EN
This article aims to contrast modern macroeconomic analysis with a nonWalrasian or evolutionary macroeconomics. This debate, which returns to the forefront with each major economic crisis, concerns the nature of coordination problems and the means of resolving them. While modern macroeconomic models describe the inter-temporal optimization behaviour of consumers who are perfectly adapted to their environment and cleared markets, evolutionary macroeconomics focuses on market imbalances that require adaptive behaviours. This contrast affects monetary and fiscal policy as well as the nature of any structural reforms to be carried out. It also affects the type of modelling to be developed
